NoScript support

As of version 0.3, the plugin now has configurable noscript support, meaning that if your user does not have javascript enabled, a simple form for uploading files using the traditional POST method can be included, which will only show if javascript is turned off. Alternately you could have a message telling the user to enable javascript, or get a decent browser.
